Will a 18 x7 rear wheel fit under the stock fender of an 06 without modification? What size tire will fit with that set up?

I want to go with a 21 x3 or 21 x 3.5 up front. Will that fit under the front fender? What size tire will fit with that set up?

Thanks for the help

 

Look for the Article in this month's American Iron about tires. It will tell you what you need to know. It's not a simple issue.
